DS4156P+

Programmable Timers And Oscillators Overview

The DS4156P+ is a ceramic surface-mount crystal oscillator from the Maxim DS4-XO series. It generates a nominal output frequency of 156.25MHz using a fundamental AT-cut crystal and PLL synthesizer technology. The device features LVPECL differential outputs, operates on a 3.3V ±5% supply voltage, and provides low phase jitter (<0.7ps RMS from 12kHz to 20MHz). It is housed in a compact 10-pin LCCC package measuring 5.0mm x 3.2mm x 1.49mm.

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead finish specifications (JESD97 category e4) prior to procurement. Check for current production status as legacy components may be subject to discontinuation notices.

Programmable Timers And Oscillators Selection Notes

Select the DS4156P+ variant specifically for designs requiring LVPECL outputs at 156.25MHz. Ensure the design accommodates the 10-pin LCCC footprint and thermal requirements. Verify that the system power supply maintains the required 3.3V ±5% tolerance to meet specified jitter and stability parameters.

Programmable Timers And Oscillators Part Context

This component belongs to the Maxim DS4-XO series of high-performance crystal oscillators. The 'P+' suffix indicates the LVPECL output type and lead-free/RoHS-compliant packaging. It shares the same physical package and core oscillator technology with other frequencies in the series, such as the DS4155D+ and DS4160P+.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same series include DS4156D+ (LVDS output) if interface compatibility allows. For different frequencies, consider DS4155P+ (155.52MHz) or DS4160P+ (160MHz), ensuring electrical pinouts and output driver types match the existing circuit design.
